I may have spoken too soon. The Pending Transfer Request Lists on the website still have names on them for every base where returning f/as have been assigned. Per the contract, the transfer lists must be cleared before any returning furloughee/new hire can be assigned to a particular base--i.e., all active f/as are given a shot at filling the slots in that base first (which would, of course, create openings in their current bases).
The fact that there are still names on the transfer lists means one of two things...
1. The base assignments for the returning f/as are "preliminary" pending the opening of the transfer lists.
2. Everyone on the transfer lists to the affected bases has already been offered transfer to those bases and has either accepted or refused transfer, and no one has bothered to update the lists on the website. After all the information is only important to flight attendants and therefore, by definition, is not critical.
In either case, the only base that would be materially affected is ORD. There are 70 people on the transfer list to ORD. If the list has not yet been opened, and 40 f/as accept a transfer to ORD when it does, then none of the returning f/as would be assigned to ORD. The assumption being that if only 40 returning f/as are offered ORD, only 40 slots are available there.
More will be revealed.
